Hi Madhu,
There is no major change in the process of "File upload" application in MDG 8.0.
Points which you are referring to are related to "Hierarchy Maintenance"
Major changes happened in the process of "Hierarchy Maintenance".
Hierarchy assignment from single-object processing for cost center, profit centers, G/L accounts, and cost elements
Within the Costcenter Maintenance UI, we have a new option to maintain the parent node (for ex: Costcenter group). Hence no separate Maintenance required to assign this Costcenter under the Costcenter group in the "Hierarchy Maintenance" UI, which we have to do in previous releases.
Please see new options related to Hierarchy Management in MDG 8.0:
Enhanced and Simplified Hierarchy Management
- Improved process for the assignment of master data
- Assignment of master data objects to hierarchies in the Single Object Processing UI
- Intuitive access to hierarchies from the search and improved switching between hierarchies
- Integrated creation of change requests in the Hierarchy Processing UI
- Control over the scope for changes, which determines how many levels of the hierarchy are available for processing in separate change requests
- Faster approval of hierarchy changes
- Display of pending change requests in the Hierarchy Processing UI
- Easy access to and intuitive display of change documents
- Enhanced processing of multiple changes
- Multiple nodes can be restructured or deleted at the same time
- Insertion of flat lists of subnodes from a file in the Hierarchy Processing UI
- A user-customizable number of subnodes is displayed when a node is expanded
